Specioation of Letters Patent.

Application led February 24, 1914. Serial No. 820,896. v

To all lwwm t may concern;

Be it known that we, ANDREAN G. RON- me, a citizen of the United States,residing at Boyd, in the county of Lac qui Parle and State of Minnesota,and ADOLPH RoNNING,

a citizen ofthe United States, residing at` Y Boyd,in the county of Lacqui Parle ,and

State of Minnesota, have invented new and useful Improvements inSilo-Filling Fixtures, of which the following is a specification. v

Our invention has for its object to provide xtures for silos of such anature as to enable one to Ell silos 'by means of ropes, slings andcarrier, said fixtures being so constructed as to be readily adjustedtotheir working positions and which may easily and compactly adjusted to asheltered position when not in use.

In the accompanying drawings which v illustrate the invention, likecharacters indicate like parts throughout, the several views.

Referring to the drawings;

Figure 1 is a side elevation of the improved xtures adjusted to theirworking positions, some parts being broken away;

Fig. 2 is a plan view of sling; Y

Fig. 3 is a front elevation of fixtures as adjusted to their positionwhen not in use; some parts being broken away;

Fig. 4 is a fragmentary view in side elevation showing especially theinner end of the so-called carrier track when adjusted into position forservice, some parts being broken awa v Fig, 5 is a fragmentary detailtaken in section approximately on line w :v5 on Fig. 4;

Fi 6 is a detail in side elevation of vertex b ook, some parts thereofbeing broken awa Elg. 7 is a detail, taken in ver-tical section showingthe construction .of the upper and lower ends of the rafter 'guidetrack;

Fig. 8 is a plan view showin`g the s ilo plate, silo roof rafters andsome of the hoistmg mechanism as attached thereto, with some partsbroken away.

Fig. 9 is a detail in vertical section showing a manner of attaching thesilo plate to the silo wall.

Fig. 10-is a detail in vertlcal section showing a modilied wa ofattaching the silo plate to the silo wall.

The general construction `of the fixtures will now be described. l Siloplate 1A is preferably formed from sheet metal in such a manner vas tooverlap and encircle the uppermost portion of the silo wall 2, and isprovided with flanges 3 through which are inserted bolts or rods 4 whichare provided at their ends with threading and threaded nuts 5. Thesilolmay be provided with members 6 which are suitably inserted or builtinto the body of the silo wall and in such a manner as t0 projectoutside of the silo wall and so as to permit rods 4 to pass throughthem. See F1gs.'1,'3, 8, 9 and 10. Rods 4 may be' of anyvconvenient lenhand construction and members 6 may be inserted in the upper or lowerportion of the silo as desired.l

A plurality of rafters 8 are suitably se! cured to the silo late 1 attheir lower ends Patented Jan. 1, 1918.

`guide ower and to a vertex b ook 9 at their upper ends.

Vertex block 9 isV provided with a ball bearing race 10 anda femalethreadingll which J 'is engaged by the male threading of the lower endof the shaft 12 and which is provided at its lower endl with a flange13. Shaft 12 passes through the center of cap 14 which overla s andcovers the upper portion of the roofp sheeting 16. Cap 14 is attached tothe roof door l5. Sil-o roof sheet- -ing 16 is preferably made out ofsheet metal -Angle lirons 19 are secured at their upper` ends to a block21 which is pivotally secured at its lower end to a carrier track 22which is provided at its lower side with flanges 23 which form a rail ortrack for wheels 24 of a carrier head 25 which is of well known and,approved construction which is provided with a pin 26 to which isattached a rope 27 which runs in its lower loop through a sling block 28which isof well known and ap- 105 proved construction and whichisprovided with pulley 29 and a hook 30. The inner end of the carriertrack 22 is provided with a pin 31 which is loosely journaled at itsends in latch pieces 32 which move in a channel and track of the rearrafter 8 in a manner as best illustrated by Figs. 1, 4, 5 and 7 andwhich is provided with inwardly turned flanges 33.

Latch pieces 32 are provided at their lower ends with teeth 34 whichengage the notches 35 which are cut in the flanges 33 near the ends ofthe said flanges 33. Latch pieces 32 are also pivotally attached attheir lower ends to lingers 36 which are of Sullicient length to foldover and cover said teeth 34 when doubled up in a manner as illustratedin broken lines in Fig. 4. v

The inner end of the carrier track 22 is also provided with a block 37which carries a 38 on which is journaled a pulley 39 over which runs therope 27.

Strap springs 40 are inclined upward and are suitably secured at theirlowersends to the carrier track 22 immediately in front of the block 37.y

A rope 41 is secured to the inner end of the carrier track 22 and runsin its upward A loop overa pulley 42 which is journaled on a pin 43which is suitably secured in the sides of the rafter-track 8.

A sling block 42 is provided with rollers 43 and a tripping point44which is constructed in any well known andapproved manner and in such amanner as to work in coperation with the tripping mechanism of the saidcarrier head 25. Block 42 is also provided with a hook which is similarin construction to the hook 30 as illustrated in Fig. 1 and in such amanner as to be easily attached to the block 45 of the sling basket asillustrated in Fig. 2. The sling block mechanism just described isconstructed in the same way as the sling blocks now ordinarily used inhoisting hay into barns and like the carrier head 25 it may be of anywell known make of manufacture employed for similar purposes. The saidslingI is preferably made of canvas 46 which is reinforced by a networkof rope 47 which is attached to members 48 and to members 49 which arelocked together bymeans of a locking mechanism 50 which is constructedin any well known manner and which is provided with a check rope 51which is employed by the operator for pulling and unlocking the ,saidlocking mechanism 50 as is ordinarily done for opening the bottom of thesling when this should be desired. Members 48 have ropes 52 attached totheir ends. Block 45 is secured to the center of one of the said 'ropes52 and the other rope 52 is provided at its 'center with a block 53.

Rope 27 as already noted is secured to pin 26 at one end and runs in itsdownward loo back and over pulleys 43 and down an over'pulley y2,9 andruns in its upward loop over a pulley 54 which is suitably ournaled` 'ibe applied at any desirable point in any well known and approved manner.J Any well known engine hoisting mecharnsm may. of course be usedinstead of horses if this should be desired.

The lower end of the door 15 may be proi'vided with rollers 56 so'as toride on a track 57 which is secured by rivets or otherwise to the siloroof sheeting -16 Rollers 56 are mounted in suitable bearings ateachvend, which are suitably attached to the under side of the said door15, with freedom to clear Vunder the door 15 and to travel on the saidtrack I57.y Door 15 may also be provided with strap hooks 58 'at itslower end which curve under and back of the lower edge of the silo roofsheeting 16 so as to prevent the said door 15 from opping in the wind.

The operation and function of the silo filling fixtures willthen be asfollows:`

.As the silo door 15 is o ened, it will be carried by and turned on t eball bearings 17, and the rollers 56 will travel on the track 57. The'rope 41 is then pulled by the o-perator and the inner end of the carriertrack 22 with its attached flanges 32 will then ride up through thechannel of the rafter-track 8 until latch teeth 34 drop into the notches35.. The raising of the inner end of the carrier track in this fashionwill cause the angle irons 19 to swing outwardly at their upper vendsuntil the carrier track 22 is approxically release block 42"with itsattached tripping point 44 whereupon the blocks 28 and `42 with theirattached sling may be lowered to the wagon below. The sling is thenspread over the bottom of the box or' the wagon. Each wagon is usuallyprovidedwith two such slings and are filled as the wagons are drawnalongside and under the lelevator of an ensilage harvester, a machinewhich cuts the standing stalks off the field, chops them into suitablelengths for ensilage and elevates the cut particles into the hoper orbox of a-wa on as already stated.

en the load is us filled it is drawn then attached to their respectiveblocks 45 and 53 of the sling. The engine or horses which may lbeattached or hitched to the loweriand free end of the rope 27 may then bestartedand the rope 27 will then move in the direction as indicated byarrows in Fig. 1, which will cause the blocks 28 and 42 to come togetherand to rise with their attached sling load of ensilage until thetripping point 44 releases the carrier head 25 from its lock hold ontripper block 59. When this is done, the carrier head 25 with itsattached sling load of ensilage will then be drawn by the rope 27 on thecarrier track 22 until the convenient point in the silo is reached,

whereupon, the operator pulls the check rope.

into the silo. By repeating these operations the silo may be easily lledand by dropping large quantities of ensilage in bunches in this wayinstead of sifting it in with an elevator or plower, and not allowingthe airto retard the fall of each particle, the ensilage in the silowill be packed more. The periodic dropping of a thousand pounds ofensilage in this way will cause the entire body of ensilage to settlebetter.

It may also be well to observe that by pulling rope 41 until the fingers36 drop into the upper notches\35 and then releasing the said rope 41,the fingers 36 will then double up so as to cover the teeth 34 in such amanner as to slide over the notches 35 and thus allow the inner endofthe carrier track 22 to drop through the channel of the rafter track 8in such a manner as to cause the angle irons 19 to be swung inwardly attheir tops so as to fold up against the rafters 8 and thus allow thedoor 15 to slide over them and cover them as the said door l5 is closed.

Having thus described our invention, what we claim as new and'desire tosecure by Letters Patent is:

1. The following elements in combination,

a silo plate, means for anchoring the said silo plate, a roof attachedto the said silo plate, means for opening .and closing a portion of thesaid roof, hoisting means attached to said silo plate and to said siloroof substantially as and for the purpose specitied.

2. A silo plate, means for anchoring the said silo plate, a roofattached to said silo plate, means for opening and closing a por-4 tionof the said roof, hoisting means attached to said silo plate and to saidroof, means for bringing the said hoisting means into a desirableposition for service together with means for releasing the hoistedmaterial from the said hoisting means so as to drop the same into thesilo. f

' 3. A silo plate, means for anchoring the said silo plate, a roofattached to said silo plate, means for opening and closing a portion ofsaid silo roof, hoisting means attached to said silo plate and to saidsilo roof, means for telescoping the said hoisting means with the saidsilo roof, means for bringing the said hoisting means into position forservico together with a second hoisting `means for bringing the saidiirst hoistling means into position for service.

4. A silowplate, means for anchoring saldsilo plate, a silo roofattached to said silo plate, means for opening and closing a portion ofsaid roof, hoisting means pivotally attached to said silo roof and saidsilo plate, means for telescoping the said hoisting means into the saidsilo roof, a second hoisting means for bringing the said first hoistingmeans into a position for service, latch pieces pivotally attached tosaid i'irst hoisting means together with carrying means incorporated insaid first hoisting means sub- A stantially as and for the purposesspecied.
